Master Bond launches Master Bond EP41S-5Med, a two-part epoxy system that meets the requirements of ISO 10993-5 for non-cytotoxicity and can be used for bonding, sealing, and coating in medical devices. It features high-temperature resistance and good strength properties. As an electrically insulative material, it can be utilized in medical electronic applications.
Suitable for Sterilization and Chemical Resistance Applications
Master Bond EP41S-5Med was tested against many sterilization methods, such as autoclaving, STERRAD®, Cidex® and Steris®, successfully resisting a hundred cycles. It is also capable of withstanding exposure to gamma radiation, ethylene oxide, as well as other aggressive sterilants and chemicals.
Master Bond EP41S-5Med provides a tensile strength of 10,000-12,000 psi and adheres well to a variety of similar and dissimilar substrates, including metals, plastics, rubbers, ceramics, and composites. This compound has a glass transition temperature of 140-145°C and is serviceable from -80°F to +450°F [-62°C to +232°C]. EP41S-5Med features reliable electrical insulation characteristics with a dielectric constant of 3.5 at 60 Hz and a volume resistivity greater than 1014 ohm-cm.
The system is black in color and contains no solvents or diluents. Master Bond EP41S-5Med offers convenient handling with a 100 to 25 mix ratio by weight. The mixed epoxy has good flow properties with a moderate viscosity of 25,000-30,000 cps. Upon cure, it offers low shrinkage and a hardness of 85-95 Shore D. Master Bond EP41S-5Med comes in standard sized units of ½ pint, pint, quart, and gallon kits. It is also compatible with automated gun dispensing systems.
